CHARLES W. SHERBURNE, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE AMERICAN LOCOMOTIVE SANDER OOMPAN Y, OF PHILADELPHIA, PENN SYLVANIA.

TRACK-SAN DING DEVICE.

SPECIFICATION forming part of Letters Patent No. 665,138, dated January 1, 1901. Application filed September 14:, 1900; Serial No. 80,016. \No model.)

To all whom it may concern I Be it known that I, CHARLES W. SHER- BURNE, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Track-Sanding Devices, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention consists in providing in the base of a locomotive sand-dome or other similar sand-holding vessel air and sand feeding passages, preferably formed in the act of casting the base of the dome and extending inward from the edge of the dome and which are adapted one to contain an air-supply pipe and the other to be connected with a sand-delivery pipe, both of which are attachable to the base in line with said passages and from the outside of the dome or vessel.

The invention will be described in detail in connection with the drawings, wherein- Figure 1 is aview, principally in plan, of enough of the base of a sand-dome to illustrate the features of the invention. Fig. 2isa view largely in vertical section upon the dot ted line 2 2 of Fig. 1. Figs. 3, 4, 5, and 6 illustrate slight modifications in the arrangement of the passages, to which reference will hereinafter be made.

A is the base of the sand-dome. In Fig. 1 it is represented as provided with the horizontal passage B, extending from its outer edge I) inward to the point I), from which extends diagonally toward the outer edge of the base the return-passage 12 which opens into an inclined passage b having an outlet "12 into the sand-delivery pipe 12 and inlet b adapted to be covered and uncovered by the hand-operated valve G,contained in the chamber of the sand-dome. The inner end of the passage b is connected with the sand-holding chamber of the sand-dome by the vertical opening or passage 12 In the horizontal passage B there is arranged an air-supply pipe D, one end of which extends outward through the casing of the dome and is connected, by means of a coupling or in any other manner, with an air-supply pipe d, running from a source of air-supply, such as the air-reservoir of the Westinghouse air-brake. The inner end of the air-supply pipe D is turned backward beneath the hole I) and so that its out-- let b will discharge into the passage o The operation of the device is as follows: Sand from the chamber of the dome feeds through the hole b to a position in front of the outlet of the air=supply pipe, and the air discharged from the end of said pipe forces it along the horizontal pipe 17 into the passage 12 to the sand-delivery pipe, by which it is fed to the rails. The sand from the dome-chamber both feeds by gravity and is d rawn to a position in front of the outlet of the air-supply pipe; but it is not fed through the passage 1) by gravity, as the said passage is horizontal and long. To obtain a gravity hand-feed, the valve C is used, and it is adapted to cover and uncover the opening 12 of the passage 11 to the sanddelivery pipe, and the pipe is so inclined that upon the opening of the valve 0 sand will fall from the chamber of the dome through it into the sand-delivery pipe. The air-delivery pipe D is attached to the base of the dome by means of a threaded holder E, which screws from outside of the dome into the threaded end 6 of said passage B. This permits the air-pipe to be readily attached from outside rectly to the passage 5 The hole 5 connecting the chamber of the dome with the passage, is arranged about midway its length. The section of the passage to the hole is the equivalent of the passage B of Figs. 1 and 2 and the section from the hole to the passage b is the equivalent of the'passage b of Figs. 1 and 2. In this modification the inner end of the air-supply pipe is not bent. In Figs. 5 and 6 I have represented the passage for the airsupply pipe as extended across the passage 12 and as provided with a return-section from its inner end to said passage. The hole for connecting the chamber of the dome with it is located at its inner end, and it is enlarged from its inner end to the passage b to provide a channel through which the sand is fed by the air to the sand-delivery pipe. The equiv alent of the passage b is found in the returnsection from the inner end of the passage to the entrance to the passage [9 Among the principal advantages of the invention are those which arise from the cheapness with which the invention may be applied to the sand-dome and engine and the various passages reached from outside the dome for the purpose of cleaning them and freeing them from obstructions.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States 1. In a track-sanding apparatus, a sanddome having a base provided with passages extending inward from the edge of the base and connected with each other within the base, both of which are connected by vertical holes with the sandholding chamber, a hand operated valve for controlling the one of said holes which connects directly with the sanddistributing. pipe and an air-supply pipe contained in the other with its on tlet beneath the hole connecting it with said chamber and arranged to blow or force the sand to the sand delivery pipe and the said air-supply pipe attachable to the base from the outer side thereof.

2. The combination in a track-sanding apparatus, of a dome having a metal base, the passages B b formed in the base by casting or otherwise, extending from the outer edge of said base inward and connected at their inner ends, said hole 6 being inclined, the hole or inlet b connecting the sand-holding chamber with the inner end of the said passage b the hole or opening 11 connecting the sand-holding chamber with the passage B, a hand-operated valve for controlling the inlet bflan air-supply pipe extending from the outer side of the base through the passage 13 and ending below the hole or opening b the portion of the passage or connection between the holes b and Z) being substantially horizontal, and the sand-delivery pipe and the air-supply pipe attached to the outer edge of the base or dome.
